About Us

Our Approach

What is “theater”? It is the art of using image, sound, space, and time to take an audience on a journey, connecting meaningfully with one or many.


People commonly misunderstand “acting” as pretending to be someone else – or worse, lying. Nothing could be further from the truth. Acting brings out what is true in each moment, word, and gesture. It teaches how to express yourself compellingly and efficiently. It develops confidence in your authentic self. It engenders a compassionate understanding of the other.


At JMS Coaching, we teach non-actors how to communicate with clarity and power. Using exercises and concepts drawn from theater training, we focus on understanding your audience, shaping your message as story, improving vocal technique, and developing physical presence. We help our clients develop practical skills that are applicable one-on-one and in public.
